Building my BFLF screen

post #1 of 13
Thread Starter 
Well I finally decided that I was going to go with a Black Flame Light fusion screen. I am going to document my building of the screen here in this thread. I will probably be asking some questions as well as I try and get through this.

I was originally going to make a 92 inch screen because I didn't think i would be able to find any acrylic mirror bigger than that. But, I ended up finding a 5x8 piece p 1/8th at a plastic supply place in brooklyn. Sweet! I also found a 5x10 piece of sintra at the same place and decided to use that for the mirror backing and forego the use of 2 pieces of 4x8 hardboard. Any time I can cut out some extra work I am all for it.

I had the Sintra cut down to 96x56" and the mirror cut to 92x52. Here are some pics of the sintra and mirror.





I then measured out my trim which i purchased at home depot. I decided to put the high side of the trim on the inside of the frame. Some people like it the other way around. I then used this pictorial by MM to miter and then wrap them in black velvet.

A little montage...



Here is how the frame looks over the sintra.



I am having a hard time finding elastomeric adhesive to put the mirror on the sintra...hoping vinyl adhesive will suffice. I am also having a problem finding the wagner to spray the screen with. Argggg. Paint should be here tomorrow.

I will update this as I go. Let me know if you see me heading for a pitfall.

Looking great so far!

Thanks, Tidder. It looks as if I will have to purchase the wagner from them. I have been trying to avoid it because I don't want to wait for it to ship. Maybe I will try looking in Jersey.

Also, does anybody know what elastomeric adhesive is usually used for? Sometimes the best place to find stuff in NYC is at specialty shops (our home depots are kinda crap). For instance, if it is normally used for flooring, I could check a flooring store.

Well, i just ordered the wagner from gleem. Looks as if this project is heading into next week. Oh well. Still need to get my mount in order.

what was the plastic supply where you found the mirrored acrylic? How much was it for the 5'x10' sheet. Also, how much was the sintra board?

Thanks for any info. I'm trying to find the same stuff to start my own project!

It sucks to have to wait to finish a project, but maybe it'll give you a little more time to organize and rethink how you will do it.

Cheers,
John

I got the plastic and mirror at a place called E and T plastics in long island city. The mirror was around $130 and the board was $65 if I remember correctly.

I am really looking forward to getting the rest of the stuff. Hope to have it all done by monday...tuesday at the latest.

You're already into this for $245 not counting paint.

The BF mix appears to be a nice light to medium gray. Can I ask one thing of you?

Would it be possible for you to get some inexpensive substrate that's half the size of your screen- half the width but full height. Put on a good primer like Kilz2, and then on the bottom (or top, your preference) a coat of UPW, and then spray the same BF mix on that panel? It is real easy to placebo ourselves when we spend a lot of money and then invest time in something to convince ourself it is truly the best, especially if it is exotic.

I'm not trying to start anything, just suggesting a valid comparison here. This could settle the 'fusion factor' once and for all.

I am taking some college classes right now on light and color and how they interact and react to different surfaces. The question really is how much light makes it through the paint, and then back through the paint without being ever so slightly out of phase with the originating light. The theory on here is it 'backlights' the image and enhances it causing a 'plasma like glow'. The other theory is if the paint is translucent enough for the light to make it to the mirror and back, there could be a very slight delay in the rebounding light which would make the image softer, possibly even fuzzy if the delay is out of sync with the source.

Since there have been enough 'Light Fusion' screens made and sold and no reports of a fuzzy image, a significant delay between the source and rebounding light doesn't seem to be an issue. Now the question is if the mirror is really making a difference. Nobody has really tested this. Light does take time to penetrate a surface, and you double that time for the return. If the pixels are already changing by the time the rebounding light comes back through the paint it won't be an additive quality to the image. In fact it will blur it, at best it will soften the image since it is out of phase.

This could be a factor for reducing SDE, but at the cost of sharpness.

With a well balanced color with the right gain you will have an excellent picture and plenty of that desired 'Pop'. The question is... is the mirror doing it or is it the paint and projector specs?

This is going to draw some heat I know, and I am not trying to derail this thread. If foofreaknfighter is willing to try this and spray the panel the exact same way he does the mirror it could be a very good test and comparison that a lot of people have been looking for.

Some of the college professors find this interesting, others feel it works in theory but not practicality. If a debate is in order then more than just an 'I say so' or 'I have seen such' is in order. This is an interesting concept but to say it is fact does need some backing up. This could be a test to back things up or refute them and indicate it's the surface color and sheen doing the work. Whatever the outcome it will be a positive thing. If there is a major difference in picture quality then we know this is worth the effort. If not, then I am sure there will be plenty of debate...

Well, I kinda hate to ruin the placebo effect for myself but I do have an extra little bit of sintra. At the very least I will spray the foot tall extra piece I have of sintra left and see what happens.

Thanks for stepping up. At the very worst you might have spent a bit more and ended up with the same screen you might have had without a mirror backing it. If someone had run the comparison before, then you would have been given a leg up on that decision. I think you are going to end up with a very nice screen no matter what so I wouldn't be worried about losing the placebo effect. However, if you can return some information on this DIY project and give a definitive yes/no on the difference then that will help the next intrepid DIYers that want to try this application.

Well, the screen is done. I think it looks pretty amazing. Much thanks to MississippiMan! I would still be looking for adhesive if he hadn't overnighted me some! Above and beyond.

I will post pictures and some more thoughts soon.

I have some more paint left, so I will try and paint a white subtrate soon.
